A charged particle enters a region of space with a uniform magnetic field B = 1.82 T. At a particular instant in time, it has velocity v = (1.34 106 + 2.54 x 106 ) m/s. Based on the observed acceleration, you determine that the force acting on the particle at this instant is F = 1.46 K N. What are the following? (a) the sign of the charged particle O negative positive (b) the magnitude of the charged particle C
